Product Overview
The M7150/M7160/M7163 Head Movable Surface Grinder is a high-performance horizontal spindle and reciprocating table grinder designed for large-scale precision machining. Focusing on 2000mm worktable length (all models), this series—including M7163×20, M7160×20, and M7150×20—combines innovative design with robust functionality. Key highlights include a conical-cylindrical plain bearing spindle for extended service life, a built-in motor structure for compactness and rigidity, and hydraulic stepless speed regulation for smooth operation. Ideal for industries requiring high-precision grinding of large workpieces, this grinder delivers consistent results, efficiency, and durability, making it a top choice for machine tool manufacturers, heavy machinery producers, and aerospace suppliers.
Key Features
Durable Conical-Cylindrical Plain Bearing Spindle
The spindle nose adopts a special plain bearing design (external conical, internal cylindrical), which reduces friction, minimizes wear, and extends the spindle’s service life. This structure ensures stable rotation even during long-term operation, maintaining precision and reducing maintenance downtime.
Compact Built-In Motor Structure
The motor is integrated into the grinder’s frame, resulting in a compact design that saves floor space while enhancing structural rigidity. This integration reduces vibration during grinding, improving surface finish and dimensional accuracy of workpieces.
Hydraulic Stepless Speed Regulation
The worktable’s longitudinal movement and the grinding head’s cross movement are powered by a hydraulic system, offering stepless speed adjustment. This allows operators to tailor the grinding speed to different materials and workpiece requirements, ensuring flexibility and efficiency.
Consistent High-Precision Performance
All models feature a vertical movement precision of 0.01mm per graduation (1mm per revolution), a workpiece surface parallelism of 300:0.008mm, and a surface roughness of Ra:0.63μm. This consistent precision meets the demands of high-end manufacturing industries.
Optimized 2000mm Worktable Design
The 2000mm-long worktable (width: 500mm to 630mm) accommodates large workpieces while maintaining stability. The maximum cross movement of the grinding head (550mm to 680mm) covers the entire worktable width, ensuring uniform grinding across large surfaces.
Powerful & Efficient Motor Configuration
With a total motor power of 17Kw, a 11Kw spindle motor, and a 5.5Kw oil pump motor, the series delivers strong grinding force for high-hardness materials. The 1440r/min grinding wheel speed (Φ400×40×127mm wheel) ensures efficient material removal and consistent results.
